Maidenhair tree, Ginkgo Biloba

The ginkgo is a living fossil, recognisably similar to fossils dating back 270 million years. Native to China, the tree is widely cultivated and was introduced early to human history. It has various uses in traditional medicine and as a source of food. Ginkgos are large trees, normally reaching a height of 20–35 m (66–115 feet), with some specimens in China being over 50 m (164 feet). The tree has an angular crown and long, somewhat erratic branches, and is usually deep rooted and resistant to wind and snow damage.

Ginkgo is a relatively shade-intolerant species that (at least in cultivation) grows best in environments that are well-watered and well-drained. In some areas, most intentionally planted ginkgos are male cultivars grafted onto plants propagated from seed, because the male trees will not produce the malodorous pulp around the edible seeds.Ginkgos adapt well to the urban environment, tolerating pollution and confined soil spaces. rarely suffer disease problems, even in urban conditions, and are attacked by few insects. For this reason, and for their general beauty, ginkgos are excellent urban and shade trees, and are widely planted along many streets. Ginkgos are also popular subjects for growing as penjing and bonsai;they can be kept artificially small and tended over centuries.
